hi, I've got a new Delonghi EAM 4500 (same as EAM 3500) and noticed, that the machine does not do a lot of frothing (comparing to my friend's machine). Can you help me? is anything I could do to maximise the frothing ability of this machine?hi, I've got a new Delonghi EAM 4500 (same as EAM 3500) and noticed, that the machine does not do a lot of frothing (comparing to my friend's machine).

I have a very similar problem - lots of steam comes through to cup - but with no milk! All items cleaned through and all rubber O rings in place; the machine is 2yrs old. DeLonghi service have been phoned (0845 600 6845) and they suggested a new jug top before worth calling engineer out. Have ordered one, unfortunately not in stock for >3weeks, so now sat waiting....... Service telephone staff have reference to an engineer for advice, to be relayed back to customer (why can't I talk to the engineer directly I wonder?), anyway apparently he suggested a new jug top should definitely improve performance, but if the problem still persisted it was probably due to congealed milk within the machine which would require a service visit.I have a very similar problem - lots of steam comes through to cup - but with no milk!

I have a very similar problem with my EAM3500S. Tons of steam comes out of the frothing jug, but no milk is ever dispensed. I have called delonghi and they advised replacing the rubber rings, which we did. They don't think a milk container lid will fix the problem and have advised sending the unit into service which means shipping it out of state. Has anyone actually discovered what is causing this problem? did you new milk lid fix it?

Here's what I did... with great success:If you've cleaned all the milk deposits from around the o rings and you still have a problem then its almost certainly the milk spout (the little pipe that directs foamy milk into your cup)

Detatch the spout and get a 2.5 mm drill bit and use it to clean all the milk deposits out of the part that plugs into the lid. Rinse through with water to clean away all the bits of hard milk.

[If you put water through the spout before and after, you will notice a dramatic difference]

Doing this completely fixed the problem for me (I had about 3 years of milk build up in mine!).

If, when you press hot water, the machine says "Heating Up" or "Please Wait" for a moment then returns to "Ready" every time then the horseshoe (steam boiler) is cold. Open the machine and check. Test the thermal fuses (TCOs) on the horseshoe, one will probably be open circuit.

If a TCO (Thermal CutOut, the white ceramic blocks on the horseshoe) is
blown, the horseshoe (steam boiler) control triac (usually BTA24-600BW)
on the main board is probably breaking down under voltage stress. You will need to
replace the main board (or just the triac if you are confident, can
upgrade to a BTA24-800) as well as any TCOs that blew. The normal
symptom for this is the machine remains in the "Heating Up" state
indefinitely, often after having reported "General Alarm" during the
event.

Fixed my problem by replacing the other heating element. The fuses were fine, but the element was open circuit. Swapped it out and all works fine (for now)!Fixed my problem by replacing the other heating element. The fuses were fine, but the element was open circuit.

I had this problem once... It turns out the electrical connection for the solenoid valve that feeds the hot water out into the milk jug/hot water tap had come loose. They are clipped on rather than being soldered into place. Trace the wires back to the main board from the solenoid (brass bit with grommets) and check that the clips are in place.

Ummn - something in your Q. seems not right. The milk is not heated directly - its only heated by the steam as it passes by (and picks up) by the milk using a venturi effect - same as a spray bottle attached to a garden hose. You say you have froth - but you can only get that if you have steam... (it does not just blow air thru to create bubbles). So froth = steam & steam = heat... so milk must be hot.
Suggest you check manual for the 'heat' settings for your expresso as this may have been changed. While this is adjustable, the milk is not.

Also always heat your cups before using them - the silver cup 'holder' at the top does a reasonable job but boiling water does far better.

I don't know why my answer posted in the comments section, so here it is in the proper area.

I had the same problem and was ready to send it in for repairs, but I
talked to a great guy at Nespresso who helped me fix it myself. The
problem was when I pushed the latte button, it would only froth milk for
a second or two and then the espresso would start pouring. It basically
refused to make a latte. Here's the things he had me do:

1)
Descale immediately. I have an older machine, and descaling once a year
does NOT cut it. He told me descaling every 5 months at the bare
minimum, if your machine is not having any problems at all. Descaling is
usually the main problem for lack of froth. I descaled and it seemed
like the machine was working better almost immediately. I also ran 4 - 5
tanks of water through the hot water spout and the main espresso part
(but mostly this is because it seems to take this much flushing to get
the smell of the descaling solution out).

2) Reset your machine
to factory settings. I have a classic Lattissima, so this is how you do
it on that machine. Turn the machine on and wait until the drink buttons
are steady (espresso and hot water buttons are no longer blinking to
warm up). Then press and HOLD the power button until the espresso and
hot water buttons BLINK THREE TIMES. Then they'll go back to steady
again. You're now back to factory settings.

I did notice that I
started having the trouble after moving the machine, so I'm not sure
which of the above solved the problem. The main thing is it worked and
I'm back to yummy lattes!

Hi When was the last time you descaled the machine, and not with vinegar? Scale can accumulate inside the boilers and insulate the water from the heating elements, produce less steam. Descale on a regular basis.

This happens either because there is not enough heat, or if you release the steam when pressure is not enough.

Very common problem with the american maid makers.

bear also in mind that Krups are not the best at frothing milk, and this is also a basic model.

If
you want the best capuccino Coffee machine, buy the italian ones,
Gaggia, Delonghi, Ariete etc. that are all great at this, or get a
bigger Krups as a replacement like the Krups XP405040 that is also good at capuccino

First, check to see if it will pump out steam without a ton of water. If it doesn't, don't use it.

Now, skim milk is terrible for it, the bubbles are too dry and
flavorless. Use 2% milk or half-and-half. It should be cold (very
cold). I put mine in the freezer in a steel frothing container for 5-10
minutes before use. Just barely submerge the wand (about .25") and turn
on the pressure. It should sound like tearing paper (not like blowing
bubbles through a straw). Do this until volume increases to around
double (if you have a frothing thermometer, it should be around 100
degrees F). Now submerge the wand farther and tilt the cup to create
swirling (this is called stretching & sweetens the milk). This
should be done until the temperature is around 140-160 degrees F. Done.

If your machine is no good for steam, there's another way: Put milk
into a steel cooking pot (I use a saucier for large groups) and put it
in the freezer. When very cold (ice forming) put on stove. Whisk
briskly while heating up on medium-high. It will create fine foam &
stretch the milk at the same time. The bubbles will start big, but
become finer as time goes by. I test by stocking my finger in &
going until it feels nearly scalding & remove from heat. Just use a
ladle for he milk & a spoon for the foam.

Place 1/3 part distilled white vinegar and 2/3 part water into the water reservoir. Turn the machine on and wait for the heat light to go off. Once the heat light goes off, turn the steam vs. water knob to the water drop icon, and turn the main function knob to steam/water. Make sure to have your frothing cup underneath the steam element ready to catch the water. The vinegar/water solution should clear out the calcium that clogs the steam element. Also, remove the cover to the steam element and dip it in a bowl with vinegar for about 5 minutes, and use something like a pipe cleaner to clean out that cover. Then apply vinegar and hot water to a rag and clean the calcium off the shaft of the steam element. Once you are all finished with this, run plain water through the espresso maker on the steam/water setting to clear out the bitter vinegar residue. Now, try again to make espresso and froth it.

Since milk contains calcium, the steam element has to be decalcified more often than a regular coffee maker. The EM-100 is a beautiful machine, but it is definitely high-maintenance - you will probably spend more time cleaning it than making cappuccino, etc.

Remove the black plastic outer sleeve of the Frothing Wand (some models have a metal outer sleeve). If done correctly, the “sleeve” has been removed, but the inner wand with red or black washer, is still connected to the machine.2) The part of the sleeve assembly that you have removed is comprised of 2 pieces, the frothing sleeve and the center piece. The center piece can be seen if you look into the top of the wand.3) Using a pencil (eraser end), or similar shaped object, push down on the center piece until an audible “click” is heard. The “click” means that the centerpiece is back into the proper position. When in the proper position, the center piece visibly sticks out the bottom of the sleeve about ¼-inch. It looks like a bird beak.4) Now put the sleeve back on the machine and your machine should be ready to froth again.
